RadGrid select and grouping feature not working on next rebind of RadGrid

[Jomar]

Hi,

I have created a RadGrid (_grdDocuments) inside RadAjaxPanel. I just need to enable multi-row selection and grouping in that RadGrid so below are the codes I have used. Data of the RadGrid is gathered thru a dropdown value say (Company1, Company2, Company3).

Initially when data is loaded in the RadGrid, you can select a row or even group the grid based on the dragged column name.

Now when you change the value of the dropdown say Company 2, you cannot select or group in the Grid anymore. Why? Am I missing something here?

This is WSS 3.0 WebPart application. No client or server events attached.

I am using Telerik version 2008.3.1314.35


Thanks

Anyone?

Ok I have found out that the cause of this is the call to RaisePostBackEvent of RadAjaxPanel of the Grid.

So instead of _pnlGrid.RaisePostBackEvent(), I have used _pnlGrid.ResponseScripts.Add(.....)

What's with the RaisePostBackEvent? Why is it locking the functionality of the RadGrid?
